The butterfly is uncommon in montane forests at low elevations (Alt. 30 - 400m).
Monastyrskii & Devyatkin (2015) recorded this taxon from Thua Thien Hue, C.Vietnam and I followed them. The subspecies identity of a photo record from Koh Phangan is not confirmed. I tentatively treat these as this taxon, but confirmation with specimens is needed.
